Method, apparatus and computer program for management of flash memory

ABSTRACT

The present application provides a method, an apparatus, and a computer program for performing integrated management of memory information to support various functions of a serial flash memory and consider performance of the memory by using the standard integrated information.

FIELD OF THE INVENTION

The invention relates to a method, apparatus, and computer program for performing integrated management of information regarding a serial flash memory.

BACKGROUND OF THE INVENTION

This section is intended to merely provide background for the invention and is not prior art to the claims.

Serial flash memories use different instructions and operate in different manners, depending on manufacturers. In order for technology standardization, the Joint Electronic Device Engineering Council (JEDEC) has been standardizing the serial flash memories (JEDEC Standard No. 216: Serial Flash Discoverable Parameters (SFDP)).

In the SFDP, a header, a parameter header, a basic parameter table, a sector map parameter table, and a basic instruction table are configured to form a tree structure. The header and the parameter header include information regarding the tables. The basis parameter table, the sector map parameter table, and the basic instruction table include information regarding the serial flash memories. In order to acquire such information about the memory, a 3-stage search process is needed, causing a time delay during the search process.

In the SFDP, functions of the memory are either supported with restrictions or not supported at all. For example, in order to restrict a write function, the SFDP only supports a block protection function while not supporting a persistent protection function and a dynamic protection function at all. Accordingly, integrated information for supporting various functions of the memory is required.

In addition, the SFDP does not consider performance of each memory. For example, a bus access mode of the memory has a different speed limit for each mode, and the SFDP does not consider the difference and is set to operate at a low speed. Accordingly, integrated information for properly using the performance of the memory is required.

Actually, because manufacturers produce models that support the SFDP together with models that do not support the SFDP, integrated management of the additional information apart from the information defined in the SFDP is required.

A memory management method and apparatus to solve the above-described problems have not been implemented yet.

SUMMARY OF THE INVENTION

The inventor of the present invention recognizes the problems of the conventional SFDP information and intends to newly define the standard integrated information that includes a pseudo basic parameter table, an additional parameter table, and a comprehensive command table.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

In the following description, when a detailed description of the known relevant functions, which would be obvious to those skilled in the art, is determined to unnecessarily obscure the gist of the present invention, the detailed description thereof will be omitted. Some embodiments of the present invention will be described in detail with reference to the exemplary drawings.

FIG. 1 is a block diagram illustrating a memory management apparatus according to an embodiment of the present invention. FIG. 1 shows a functional block representing a memory 10. Generally, examples of the memory include volatile memories, such as a dynamic random access memory (DRAM) and a static random access memory (SRAM), and non-volatile memories such as an electrically erasable programmable read only memory (EEPROM), a ferroelectrics random access memory (FRAM), a phase-change random access memory (PRAM), a magnetic random access memory (MRAM), and a flash memory. The volatile memory may lose stored data when power is cut off, and the non-volatile memory may conserve stored data even when power is cut off. Particularly, the flash memory advantageously has high programming speed, low power consumption, large data storage capacity, and the like, and thus is widely used as a storage medium in a computer system, etc. The flash memory is divided into a parallel flash memory and a serial flash memory. A parallel flash memory has cells arranged in parallel between a bit line and a ground line while a serial flash memory has cells arranged in series between the bit line and the ground line. For the memory management apparatus according to the embodiment, the serial flash memory is described as an example. However, embodiments of the present invention are not limited thereto and may also be applied to a different type of memory if necessary.

As shown in FIG. 1, a memory management apparatus 100 according to the embodiment includes a memory information read unit 110 and a memory feature setting unit 120.

The memory information read unit 110 uses a first instruction to read standard integrated information from at least one of a memory 10 and an application image 20. The memory information read unit 110 uses a second instruction to read standard information from at least one of the memory and the application image 20.

The application image 20, which is a data file that includes a type of program for driving a product equipped with the memory 10, may be implemented in hardware, firmware, software, or a combination thereof.

The first instruction and the second instruction correspond to predesignated instructions that may read information regarding the memory 10. The first instruction and the second instruction are different from each other. Here, the first instruction is an instruction that is arbitrarily designated by those skilled in the art. For example, a typical read instruction is represented as a hexadecimal value 03 h, but is not limited thereto. The second instruction is an instruction that has been designated during standardization. For example, the instruction designated in the standard is 5 Ah, but is not limited thereto.

The standard integrated information denotes a group of information that is newly defined to widely include information regarding the memory 10. The standard information denotes an information group that is predefined to include some of the information regarding the memory 10. Details of the standard integrated information and the standard information will be described below with reference to FIGS. 3 and 4.

The memory feature setting unit 120 uses the standard integrated information or the standard information to set a feature of the memory 10. The feature of the memory 10, in addition to basic operation for reading data from or writing data to the memory 10, conceptually includes whether to perform various operations on the memory 10, the extent of the operation, and the attribute needed to operate the memory 10 for a specific purpose.

The memory feature setting unit 120 may set a bus access mode of the memory 10 as any one of a plurality of bus access modes defined in the standard integrated information or the standard information. For example, representatively, there may be a serial peripheral interface (SPI) in the bus access mode. Here, the SPI uses one pin of the memory to input a command, an address, and data.

The bus access mode may be extended to a dual serial peripheral interface (DSPI) and a quad serial peripheral interface (QSPI) in addition to the SPI. In terms of hardware, the DSPI uses two pins of the memory, and the QSPI uses four pins of the memory.

A plurality of defined bus access modes may be formed by combining one or more pins associated with the command, one or more pins associated with the address, and one or more pins associated with the data. For example, the combination may be made of one pin associated with the command, one pin associated with the address, and one pin associated with the data. Alternatively, the combination may be formed by two pins associated with the command, two pins associated with the address, and two pins associated with the data. Alternatively, the combination is formed by four pins associated with the command, four pins associated with the address, and four pins associated with the data. Here, the number of pins associated with the command, the number of pins associated the address, and the number of pins associated with the data need not be equal. Basically, the command, the address, and the data are formed in units of bytes.

The memory feature setting unit 120 may set a protection function for the memory 10 as at least one protection type among a plurality of protection types defined in the standard integrated information or the standard information. Examples of the plurality of defined protection types may include block protection, persistent protection, and dynamic protection for restricting a write to the memory.

The memory feature setting unit 120 may set a sector map of the memory 10 in at least one of a plurality of sector units defined in the standard integrated information or the standard information. For example, the plurality of defined sector units may include 4, 32, and 64 Kbytes (KB).

The sector map has map information regarding sectors. Here, the sector is a basic unit of a memory region and denotes a unit in which the memory performs an erase operation. A flash memory performs a read operation, a write operation, and an erase operation, and the respective basic units of the memory region needed to perform the operations are different from one another. In addition, speeds for performing the operations are different from one another. In order to enhance the operating speed of a flash memory, the number of times each operation is performed and the size of the memory region need to be considered.

FIG. 2 is a detailed block diagram illustrating a memory management apparatus according to an embodiment of the present invention. As shown in FIG. 2, a memory management apparatus 200 according to an embodiment of the present invention includes a memory information read unit 110, a memory feature setting unit 120, a memory information determination unit 230, a memory information write unit 240, and a command execution unit 250. These components may be implemented as a single device or separate devices that are spaced apart from one another. The memory information read unit 110 and the memory feature setting unit 120 shown in FIG. 2 have been described with reference to FIG. 1. Accordingly, the following description will be made on the assumption that these components are provided.

The memory information determination unit 230 determines whether the standard integrated information is present or whether the standard information corresponds to a designated model or an undesignated model.

The designated model denotes a standard that is designated among a plurality of versions which may be created when the standard defined by the Joint Electronic Device Engineering Council (JEDEC) is revised. For example, the designated model may include JESD216A and JESD216B.

The undesignated model denotes a standard that is not designated among the plurality of versions. For example, the undesignated model may include JESD216.

The memory information write unit 240 writes or changes all or some of the standard integrated information to at least one of the memory 10 and the application image 20. For example, the memory information write unit 240 writes the standard integrated information, such as a protection type, a bus speed limit, a mini sector map, and a comprehensive command, to the memory 10, changes the contents of the information, or changes a memory region and then writes the contents of the information to the changed memory region. The memory information write unit 240 writes the standard integrated information, such as a protection type, a bus speed limit, a mini sector map, and a comprehensive command, to the application image 20, changes the contents of the information, or changes a memory region and then writes the contents of the information to the changed memory region.

The command execution unit 250 executes a command defined in the standard integrated information. A manufacturer may define various commands so that the memory may perform various functions, as needed. The command execution unit 250 executes these commands For example, examples of the defined commands may include a one-time programmable (OTP)-associated command, a memory-security-associated command, etc.

FIG. 3 is a diagram illustrating standard information according to embodiments of the present invention. As shown in FIG. 3, the standard information, which is an information group that is previously defined to include some of the information regarding the memory, includes a header 310, parameter headers 320, 330, and 340, a basic parameter table 350, a sector map parameter table 360, and a basic command table 370. For example, the standard information may include the standard of serial flash memories defined by the Joint Electronic Device Engineering Council (JEDEC) (JEDEC Standard No. 216: Serial Flash Discoverable Parameters, (SFDP)).

The header 310 includes information regarding the number of parameter headers. For convenience of description, FIG. 3 illustrates three parameters, but the standard information may include a different number of parameter headers. The parameter headers 320, 330, and 340 include information regarding an address and a length of a table. The table includes information needed to perform an operation of the flash memory.

The basic parameter table 350 includes basic information of the flash memory, a bus access mode, and information regarding a read method and an erase method of the bus access mode. The sector map parameter table 360 includes information regarding an erase command and a sector map, which are supported differently depending on the size of the sector. The basic command table 370 includes information regarding a command that supports an address formed of 4 bytes.

As shown in FIG. 3, the header 310, the parameter headers 320, 330, and 340, the basic parameter table 350, the sector map parameter table 360, and the basic command table 370 are configured to form a tree structure. The sizes of the header 310, the parameter headers 320, 330, and 340, and the basic command table 370 may all be two double words (DWORDs) or eight bytes. The size of the basic parameter table 350 may be sixteen DWORDs. The size of the sector map parameter table 360 may be fourteen DWORDs. Embodiments of the present invention are not limited thereto.

When the standard information is used to acquire the memory information, a read operation may be repeated several times in the bus access mode formed by combining one pin associated with the command, one pin associated with the address, and one pin associated with the data. In order to acquire information written in the table, a 3-stage search process is needed from the beginning of the header 310, thereby causing a time delay. Here, the 3-stage search process denotes reading a header, reading a parameter header, and reading a table. Accordingly, the number of searches may be from three up to seven.

FIG. 4 is a diagram illustrating standard integrated information according to embodiments of the present invention. As shown in FIG. 4, the standard integrated information, which is an information group that is newly defined to widely include the information regarding the memory, includes a pseudo basic parameter table 410, an additional parameter table 420, and a comprehensive command table 430.

The pseudo basic parameter table 410 may be substituted for the basic parameter table 350 and may include the basic parameter table 350. In other words, the pseudo basic parameter table 410 does not include the header 310 and the parameter headers 320, 330, and 340 included in the standard information. The pseudo basic parameter table 410 includes an identity (ID), a parameter length, etc.

The additional parameter table 420 is a table for adding an undefined memory feature to the standard information and includes information regarding a protection type for restricting a write operation on the memory, a mini sector map for replacing the sector map table, and a performance level that may be set for each bus access mode.

For example, the protection type may include block protection, permanent protection, and dynamic protection, and the performance level that may be set for each bus access mode may include a speed limit for a bus access.

The comprehensive command table 430 may include various commands for enabling the memory to perform various functions. For example, examples of the commands may include a one-time programmable (OTP)-associated command, a memory-security-associated command, etc., and may include various commands defined by a manufacturer as needed.

The sizes of the pseudo basic parameter table 410 may be sixteen DWORDs. The size of the additional parameter table 420 may be seven DWORDs. The size of the comprehensive command table 430 may be twenty-one DWORDs. Embodiments of the present invention are not limited thereto.

Unlike the standard information having the tree structure of FIG. 3, the standard integrated information shown in FIG. 4 may be formed in a simple combination on the pseudo basic parameter table 410, the additional parameter table 420, and the comprehensive command table 430. Thus, a complicated search process such as the 3-stage search is not needed to obtain the memory information, and thus the search speed may be improved.

FIG. 5 is a flowchart illustrating a memory management method according to an embodiment of the present invention. The method is a memory management method of the memory management apparatus 100, which has been described with reference to FIG. 1.

In S510, standard integrated information is read from at least one of the memory 10 and the application image 20 using a first instruction. Here, the standard integrated information is standard integrated information that has been described with reference to FIG. 4, and includes the pseudo basic parameter table 410, the additional parameter table 420, and the comprehensive command table 430.

The memory management apparatus 100 may complete searching for the memory information with one read process. In this case, a bus access mode formed by combining one pin associated with the command, one pin associated with the address, and one pin associated with the data is used.

The first instruction is an instruction that is arbitrarily defined by those skilled in the art. For example, a typical read instruction is represented as a hexadecimal value 03 h, but is not limited thereto.

In S520, a feature of the memory 10 is set using the standard integrated information. Here, the feature of the memory 10, in addition to basic operations for reading data from or writing data to the memory 10, conceptually includes whether to perform various operations on the memory 10, the extent of the operation, and the attribute needed to operate the memory 10 for a specific purpose. For example, the feature of the memory 10 may include a bus access mode, a protection function type, a sector map unit, etc.

According to the embodiments, by using standard integrated information newly defined to widely include the information regarding the memory 10, it is possible to use the memory without restricting the function of the memory, achieve the maximum performance for each memory, and allow a manufacturer to use various commands needed for each memory.

FIG. 6 is a flowchart illustrating a memory management method according to another embodiment of the present invention. The method is a memory management method of the memory management apparatus 200 which has been described with reference to FIG. 2. Unlike the memory management method described with reference to FIG. 5, the embodiment further includes determining whether the standard integrated information is present or determining whether the standard information corresponds to a designated model or an undesignated model.

In S610, the standard integrated information is read from at least one of the memory 10 and the application image 20 using a first instruction. Here, the standard integrated information is standard integrated information that has been described with reference to FIG. 4, and includes the pseudo basic parameter table 410, the additional parameter table 420, and the comprehensive command table 430.

In S620, the memory information determination unit 230 determines whether the standard integrated information is present. Here, the standard integrated information is the standard integrated information that has been described with reference to FIG. 4.

In S630, the feature of the memory 10 is set using the standard integrated information. Here, the feature of the memory 10 conceptually includes, in addition to basic operations for reading data from or writing data to the memory 10, whether to perform various operations on the memory 10 and the attribute needed to operate the memory 10 for a specific purpose. For example, the feature of the memory 10 may include a bus access mode, a protection function type, a sector map unit, etc.

The memory management method according to the embodiment may additionally include reading the standard information (S640). In S640, when the standard integrated information is not present, the memory information read unit 110 uses a second instruction to read the standard information from at least one of the memory 10 and the application image 20.

Here, the second instruction is an instruction that is previously defined during standardization. For example, the second instruction is represented as a hexadecimal value 5 Ah, but is not limited thereto.

In S650, the memory information determination unit 230 further includes determining whether the standard information corresponds to the designated model (S650). Here, the designated model is a standard that is designated among a plurality of versions, which are created during the standardization as the standard information. For example, the SFDP may include JESD216A and JESD216B.

In S660, when the standard information corresponds to the designated model, the memory feature setting unit 120 sets the feature of the memory 10 using the standard information.

When a result of the determination in S650 is that the standard information does not correspond to the designated model, a typical memory operation is performed without needing to use the standard information. For example, when the standard information does not correspond to the designated model, there may be an undesignated model, undefined information, etc. Here, a typical memory operation may include a data read operation. For example, the read operation may be performed in a bus access mode formed by combining one pin associated with the command, one pin associated with the address, and one pin associated with the data. In this case, the instruction may be 03 h, but is not limited thereto.

According to the embodiments, by using the standard integrated information newly defined to widely include the information regarding the memory 10, it is possible to manage existing standard information, for example, a model that does not support the SFDP, together with a model that supports the SFDP, and thus it make an advantage of unifying management of the memory models without needing to manage a serial flash memory model for each version of the SFDP.

A memory management method according to another embodiment of the present invention will be described below. Unlike the memory management method described with reference to FIGS. 5 and 6, the memory management method according to the embodiment relates to a method of performing integrated memory management while booting a product equipped with the memory or downloading an application image.

The memory management method according to the embodiment corresponds to a method of managing the memory, which is installed in the product driven with the application image, using the memory management apparatus. The memory management method according to the embodiment includes using the standard integrated information including the pseudo basic parameter table, the additional parameter table, and the comprehensive command table to set the feature of the memory when the product is booted.

Here, the application image, which is a data file including a type of program for driving a product equipped with the memory 10, may be implemented in hardware, firmware, software, or a combination thereof.

The memory management method according to the embodiment may further include at least one of containing the standard integrated information in the application image, downloading the application image including the standard integrated information in a storage medium, writing or changing all or some of the standard integrated information included in the application image or the memory, and setting some region of the memory for writing the standard integrated information.

Generally, the memory management method includes downloading the application image again after downloading download software for programming a flash memory. One download process may be omitted by building the memory management method, apparatus, and computer program according to embodiments of the present invention into a system on chip (SOC). Accordingly, two download processes may be reduced to one download process.

According to the embodiments, it is possible to support various functions without uniformly restricting the performance of the memory, thereby operating the memory at an optimal speed during an initial booting process. Thus, the booting speed of the product equipped with the memory may be improved.

Although the steps of FIGS. 5 and 6 have been described as being sequentially performed, this is only an exemplary description. It will be appreciated by those skilled in the art that various modifications and changes may be made by changing the orders described in FIGS. 5 and 6, executing one or more steps in parallel, or adding another step, without departing from the essential characteristics of embodiments of the present invention.

The apparatus may be implemented using a hardwired device, a field programmable gate array (FPGA), an application specific integrated circuit (ASIC), etc. In addition, the apparatus may be implemented as an SOC including one or more processors and controllers.

The method according to the embodiments may be implemented as program instructions executable by a variety of computers and recorded on a computer-readable medium. The computer-readable medium denotes any medium that participates in providing instructions to a processor for the execution. The computer-readable medium may include a program instruction, a data file, a data structure, or a combination thereof. For example, the computer-readable medium may include a magnetic medium, an optical recording medium, and a memory and may be embodied in the form of a transmitted signal wave. The computer program may also be distributed throughout a computer system connected over a network so that the computer-readable codes may be stored and executed in a distributed fashion.
